Wrecks booty (6)
I believe the answer is:
spoils
This clue is a double definition.
'wrecks' is the first definition.
(both can mean destroys or damages)
'booty' is the second definition.
(both can mean the proceeds or prize from something)
(Other definitions for spoils that I've seen before include "Cossets, fails to instil discipline into" , "Damages" , "Mars - plunder" , "Mars the loot" , "Booty" .)
